Sidney J. Weinberg Jr, a senior director of Goldman Sachs, died aged 87 at his home in Massachusetts on Monday. His family's links to the Wall Street giant have existed since his father, Weinberg Sr, first joined as a janitor’s assistant to clean spittoons and brush hats in 1907.

His father's rags-to-riches tale and meteoric rise through the ranks of Goldman Sachs to chief executive in 1939 until his death in 1969 has been well documented. So too has the life of his younger brother John L. Weinberg, who came to be known as the conscience of Wall Street. John joined Goldman in 1976 as partner until 1990. He died in 2006.
